As I said, my problem is that the cycle starts fine. When you start the opening process, the tonneau cover would open fine (and not slow). The back part of the top would move up and forward fine. But then the next part of the cycle of the front moving back is when it couldn't keep going and I have to start helping it by pushing the front part of the top back. Once the front part has moved back to above the boot container then it could slowly continue by itself..

when I close the top, tonneau cover open fine, but I need to pull the top up and forward to help it out. Once it gets to the part of the cycle when the back moves up for the cover to move down then it could complete the cycle by itself.

So is it like the middle 2/3 part of the opening and closing cycle is when you need the most hydraulic power?

WP. That's just how mine was acting. It forward part of the roof would do it's little wheelie pivot, the tonneau would open up, then the roof was supposed to continue. This is where I had to give it that little nudge. That turned into a bigger nudge after a few weeks. Finally, the top would have problems getting out of the boot container and required some help. That's when I knew it was pump time.

Where in FL are you? I'm in Jax.

Manually open and close the top, it'll give you an appreciation for when the pump has to work hardest.

Heh, I almost have to do that. thought the top was gonna completely quit a few week ago. Had to turn of the key and let it chill for like a few mins then I was able to get it to complete the cycle.

Yeah, its summer time in FL and my top is deciding to take a vacation too instead of working!

I recently read that the top won't cycle if the fluid is too hot. Can't remember what the temp for non-function was however.

I work at the south end of Southside, near the Avenues mall and live just outside of Duval in St. Johns. Shoot me a PM if you want to hook up and I can show you how easy this is. Honestly, you need only like 1 wrench.....and some trim removal tools don't hurt to get the trunk liners out. It's going to be obvious if you have a leak at the motor\pump. It's wrapped in a foam shell, so that'll act like a sponge and catch the oil.

INPA didn't show any error regard temperature induced shutdown in my case...

You are talking about when everything is ready to go back into the storage compartment at once after all the pre-close moving right? When the whole top is supposed to kind of fall back but it doesn't. Mine will do that but sometimes it locks (usually if you hold the button for a while and it tries but gets nowhere) into that position and I have to put it back up manually. Sounds like it is my pump as I've found no fluid.

I didn't bother to return the Mercedes fluid, not worth my time. If anyone local needs it, they can have it.

Good idea on finding a friend to swap pumps. It really doesn't take long at all.
Can you take a picture of your pump installed? Mine was taken off and I don't know how to put it back. Also, does yours have oil filled all the way to the top?

I was told that one can only manually close the top, but not open the top manually? Is this information wrong?

To get a good pic of the pump, I'd have to remove a lot of stuff. Check out the DIYs @ http://www.tophydraulicsinc.com. They have very good pics and links to some forum posts. Youtube has some videos too.

As for the level, there's a dot on the reservoir where the fluid should be up to. That needs to be checked with the top down, so the oil is out of the cylinders.

You can raise and lower the top manually. The instructions are in the owner's manual, but it's pretty straight forward. There's a hex wrench behind the rear armrest that you can use to move the windshield latches.

I opened the hood all the way down, locked it till I can open the trunk.

I took the motor out off the solenoid block, and filled it up to the round circle indicator on the reservoir.

Still the roof won't go up. It just unlocks the tonneau, and the motor makes a buzzing sound. (Noone seems to mention about the loud sound in the DIY writeups.)

Not sure if I have a solenoid problem? I would reckon the tonneau cover would rise first but it just stays there (roof fully open). The new motor makes a sound but its not doing anything. Am actually at a loss on what to do at the moment.

Is there a way to check where the electrical wires go to the pump? The connectors are all the same size (pairs)

If you found no leaking fluid, it's probably the pump not working correctly and need to be replaced. I think my symptom before replacing the pump was like yours.

So you got a rebuilt pump and your top and tonneau still won't move?

when looking directly at the bottom of the pump, and with the two pairs of small connectors oriented to be more inferior (with the notch for the wire bundle on the right side), the small wire with green strip goes to the right small connector. The large wire with the darker almost black wire goes to the right large connector

Thank you, that's the way I guessed them to be then. So this wiring is right, something else is the problem.

pump pic

You need to take the top foam cover and attach to side of car. The other pic shows close up of hydraulic hoses.

Thanks, I have them looking like your photos now. Still the motor makes a sound but nothing is happening with the top.

If you already got the 4 bottom connectors connected correctly as well as also having the green electrical plug at the top of the pump in place as well as making sure all 6 hydraulics lines are connected correctly (by their numbers) and there is no leak in the system then it should work..

Unless something in the pump assembly is damaged. Was this a rebuilt pump from tophydraulics or did you buy some used components? I was warned to not buy used pump b/c they might be on way out and they are not as good as the rebuilt pump and cost about the same as rebuilt on ebay anyway....

What tophydraulic sent me was the complete pump assembly of the reservoir as well as that metal component on the top of the pump where the green electric plug and hydraulic lines are connected to.

If this is a used pump your mechanic put in, it might be worth it to send the whole pump assembly to tophydraulics for diagnostic.
